Patented Feb. 4,1919.

Original application filed February 24, 1910, Serial No. 545,599. Divided and this application filed March 30, 1916. Serial No. 87,717.

To all whom it may concern:

Be it known that I, HOWARD D. CoLMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new.

and useful Improvements in Winders, of which the following is a specification.

This invention relates to machines for rewinding yarn from bobbins onto spools,

cheese cores or other suitable yarn carriers. One of the objects of this invention is to provide means for throwing the cheese, spool or the like, out of operation when the thread being wound is exhausted through breakage of the thread or through the complete un- A further object is to provide means for holding the yarn-traversing element out of operation while the cheese or spool is in thrown-out position.

Figs. 21 and 22 are, respectively, a front elevation, partly in section, and a top plan view of the spool support and related devices, showing a different form of brake from that illustrated in Figs. 14, 15 and 18. In Figs. 21 and 22 the brake is represented as in the released position. Fig. 23 illustrate a means for holding the spool out of contact with the spool-rotating means.

This application is a division of application Serial Number 545,599, filed February 24th, 1910, (Patent No. 1,183,276,) and a continuation in part of application Serial Number 167,703, filed July 31st, 1903, (Patent No. 1,187,971.) The machine shown in Patent No. 1,183,276 co'mprisesa spooler,

' that is to say, a machine for winding yarn from bobbins onto spools, and a windertending mechanism arranged to travel along the spooler and tie the ends of the yarn on reserve bobbins to the ends of the yarn on the spools. It will be understood, however, that certain of the improvements disclosed in the present application are adapted for use in winders of other types.

The embodiment herein shown of my invention comprises a framework providing two parallel sides, each side being equipped with means for supporting bobbins and means for supporting and rotating spools. As shown in Figs. 1 and 3, the framework of the machine may comprise a number of transverse frames 1 rigidly united' by suitable longitudinal members, as, for example, the rods 2 and the two angle-irons 3.

The bobbins may be supported in any ordinary or preferred way; for example, they may be non-rotatably mounted for the drawing-of the yarn off the tips of the bobbins or theymay be rotatably supported for the unwinding ofthe yarn from the sides of the bobbins. The present drawings illustrate bobbin-holders of the type shown 1n Patent No. 1,045,879, dated Dec/.3, 1912.

3) fixed to slides 14 which are slidably mounted upon vertical guides 15 attached to the frames 1. To a rock shaft 16 are fixed a suitable number of levers 17 which are conneoted by means of links 18 to the slides 14.

' The shaft 1.6 is rocked to raise and lower the build-rails alternately by means of a cam 19 (Fig; 3) engaging a roller 20 on an arm 21 fixed on said shaft, and a weight'22 carried by an arm 22 on the shaft 16, the weight holdingthe roller a ainst the cam. The cam is mounted on a sha t 23 which carries at one end a spur gear wheel 24 meshing with an intermediate gear 25, the latter meshing with a pinion 26 fast on a shaft 27.

On the shaft 27 is a worm wheel 28 meshing with a worm 29 on a vertical shaft30.

Power to rotate the shaft 30 is derived from any suitable source, as a countershaft (not shown) geared to a shaft 31 which is coupled to the-shaft 30.

For each spool there is a build-bar 32 (Fig. 4) the lower end of which carries a pin 33 resting on the build-rail 13, the yarn being guided by the bent upper end of the buildbar. As the rails 13 alternately rise and descend, the-bars 32 direct the yarn tovarious heights upon the spools, thus causing the yarn to be wound evenly on the spools.

The spools may be rotated in any usual or desired manner; herein they are shown as rotated by contact of the yarn mass with a continuously-moving endless belt 34 carried by a pulley 35 fixed on the shaft 30 and a similar pulley (not shown) at the other end of the machine frame. Intermediate said pulleys the belt is confined between idlers 36 placed at suitable intervals at opposite sides of the belt. See Fig. 3.

Referring now to Fig. 1: 37 are laterallyextending arms attached to the frames 1 and supporting bars 38. Brackets 39 (Figs. 1 and 2) are fixed to the outer end of the arms 37 and at intervals to the bars 38, and in these brackets are journaled shafts 40 which are rotated by any suitable means, as. for example, by means of sheaves 41 and belts 42 running to any convenient source of power,

such as the countershaft before referred to. On each shaft 40 are fixed peripherally-grooved tension-reducing guide-rolls 43 (Figs. 8V and 9), one for each spool, over which rolls the yarn runs in passing from sure that any breakage of the yarn due to weakness shall occur between the bobbins and the rolls. 44 (Figs.8-and 9) are threadguides fixed-upon the bars 38, the running threads extending through said guides.

When the thread exhausts, the end of the thread would become wound upon the spool unless prevented from so doing, and the thread-end would have to be found before the thread could be tied to the thread of the reserve bobbin. In order to prevent the exhausted thread from being wound on the spool, the rotation of the spool is stopped by means of a brake hereinafter described. To keep the exhausted thread under control and prevent it from jumping out of its proper position, I provide means for clamping the thread when it exhausts. Adjacent to each of the guides 44 is a thread clamp, the stationary member of'which clamp consists, in this instance, of a round rod 45 (Fig. 8) lying in a rabbet' formed in the bar 38 and attached to a bracket 46 screwed to said bar. The movable member 47 of the clamp is mounted upon a pivot 48 and is adapted to swing down into position to clam the thread against the member 45. A coiled spring 49 (Fig. 9) bears against one side of the clamp member 47. To an between the rolls and the spools, and thus inthread running through the adjacent guide 44 exhausts, by means comprising a fork 56 fixed on a rock shaft 57 supported by the bracket arm 50, said fork consisting of a' short tine 58 and a longer tine 59 between which the lower end of the lever 52 normally lies. Fixed upon the shaft 57 is a detector fork 60 having bent tines 61 that are arranged to alternate with fingers 62 forming a grid which is mounted on an arm 63 that is fixed to the bracket 46. On its way ,to the spool, the running thread extends from the active bobbin, over a guide pin 64, between the tines 61 and the fingers 62, and part way around the tension-reducing roll 43, the tension on the thread due to the drag of the bobbin preventing the detector fork 60 from swinging far enough short tine 58 of the fork 56.

interference between the active thread and to the right (Figs. 4 and 9) to permit the lower end of the lever 52 to sli past the 0 prevent the reserve thread, said threads are caused to pass at opposite sides of a finger 64 fixed to the pin 64. 65 are stops for limiting the swinging movement of the detector fork 60.

A stop 254 (Fig. 10) is pivoted on the lower side of the bar 38 in position to lie in the path of movement of the detector fork 60 when the latter is moving toward its operative position. An arm 255 on said stop carries a pin 256 arranged to be engaged by a cam (not shown) on the carriage of the traveling winder-tending mechanism, to swing the stop out of position to interfere with the movement of the detector fork. A spring 258 tends to swing the stop into operative position.

Referring to Figs. 4 and 7, a shield 66 is fixed to the bar 38. In the vertical plane of each roll 43,-'a slot 67 is formed in the shield, for the entrance of the threads, as will appear more fully hereinafter.

For the free end of the yarn on each reserve bobbin there is provided a spring clamp 68 attached to the bar 38. A projection 68 (Fig. 8) prevents the thread from being inserted too far back into the clamp, and insures that the thread shall have a definite operative position with relation to the device (not shown) for taking the thread out of the clamp.

Between the tension-reducing roll 43 and the thread-clamp 45 47 the yarn passes around an idler roller 69 (Fig. 8), whereby a. reserve-supply loop is formed in the thread to give sufficient length between the bobbin-holder and the spool so that the spool may be stopped before the end of the thread, when exhausted, has passed too far to be operated upon by the winder-tending mechanism. Said roller is mounted upon a slide arranged for vertical movement upon a guide bar 71, loops or straps 72 (Fig. 4) on said slide serving to guide the latter in its movements along the guide bar. The idler roller 69. is inclosed within a housing 73 having a slot 74 (Fig. 8) in its walls to permit the thread to run in contact with the roller, said slot having a flaring entrance Upon the upper end of the slide 70 is a deflector 76 the purpose of which will appear hereinafter.

in Fig. 4. The device 69 70 Will be hereafter termed the looper. It has a lug 241 (Fig. 4) by means of which it is'raised to the position shown in Fi l3ewhen a loop is to be formed in a new t read.

Secured to the angle-irons 3 arebrackets 77 (Fi s. 14 and 15) having alined bearings 78 79 t ereon. 80 is a shaft, the upper portion of which is supported in the bearing Normally the slide 70 rests upon the rail 6, as shown 78. Upon the lower part of the shaft is loosely mounted a sleeve 81 which is rotatably mounted in the bearin 79.

The spool-spindle is carrie by a frame 83 comprising the vertical sleeve 84 and the arms 85 86, said arms being loosely mounted on the upper end of the shaft 80 and the sleeve 81, respectively. Fixed to the shaft 80 is a finger 87 (Fig. 14) carrying a pin 88. A coiled spring 89 surrounds the shaft 80 and the sleeve 81 between the bearings 78 79 and bears at its ends against the pin 88 and a pin 90 set in a ratchet disk 82 (Figs. 15 and 16), said disk being rigid with the sleeve 81. The tension of the spring may be adjusted by rotating the disk 82, the disk being held in the desired position by means of a pawl 91 which is mounted on an arm 86 which is rigid with the arm 86. On the upper end of the shaft 80 is fixed a crank arm 92. A link 93 is attached at one end to said crank arm and at its other end to a slide 94 (Fig. 11), which slide is movable longitudinally of a slotted guide bar 95 fix d to the bracket 46. To the lower end of the slide 94 is-attached a link 96 (Fig. 9) that is connected to the lever 52 at 97. When the fork 56 holds the lever 52 from movement, the shaft 80 cannot rotate, hence the pin 88 forms a stationary abutment for the spring 89, which latter tends to swing the frame 83 in the direction to throw the spool against the constantly moving belt 34. I

The spool-spindle 98 is rotatably mounted in the sleeve portion 84 of the frame 83. Lubricating oil may be admitted to the interior of the sleeve 84 through ducts 100 101 (Fig. 17). 102 is a cap for closing the inlet end of the duct 101, said-cap being fixed to an arm 103 which is pivoted at 104.

The spool rests upon a disk 105 fixed to the spindle 98, said disk having studs 106 thereon to fit into recesses in the lower end of the spool and thus prevent. rotation of the spool with relation to the disk 105. Said ClISk has a peripheral flange 107 arranged tobe engaged by a suitable brake device, as, for example, a shoe 108 (Figs. 15 and 18) attached to a stem 109 which is pivotally connected with the crank arm 92 concentrically to the shaft 80. The brake shoe is slidable between lugs 110 (Fig. 18). When the detector fork 60 permits the shaft 80 to move, the spring 89 turns said shaft and presses the brake shoe 108 against the flange 107, thereby stopping the rotation of the spool. Both ends of the spring are now bearing against the frame 83, consequently said spring exerts no tendency to swing the frame. Immediately upon the application of the brake, the momentum of the spool is absorbed by the pivoted frame 83, and said frame immediately swings away from the belt 34. The momentum of the spring 89 and the arm 92 also plays a small part in locking the spool out "of contact with the belt. The teeth on the collars 111 and 112 permit of a little play between them.

In Figs. 21 and 22 I have shown a band brake 113 which may be used in lieu of the brake shoe 110. One end of the brake band is atached to the arm 85 and the other end .to the crank arm 92.

To counteract any tendency of the disk 105 to rise during its rapid rotation, a hook 103 (Fig. 17) is provided upon the arm 103, said hook overlying an inturned flange 107 a on the flange 107.

During the resetting of the detector mechanism by the winder-tending mechanism hereinbefore alluded to, the-latter holds the spool out of contact with the belt 34 by means of'a cam (not shown) acting upon an arm 114 fixed to the frame 83.

Referring to Fig. 5, the build-bars 32 are guided in their vertical movements by means of guides 115. 116, the guides 115 being rigidly fixed to the "brackets 77. It is desirable to retain each build-bar in its most elevated position during the operation of tying a reserve bobbin to the yarn on the spool, to attain which end I provide in the present embodiment the following-described means: The guide 116 is pivoted at 117 (Fig.

I "as -14) and is normally held in such position that the build-bar can pass freely through the guide, by the finger 87 the guide having a stem 118 (Fig. 20) which rests on the finger. When the finger is withdrawn by the brake-applying'movement of the shaft .80, the guide 116 drops into the position indlcated in Fig. 19 whereupon the downward movement of the build-bar is prev, vented by reason of binding of said bar in the guide. It will be seen that should the finger 87 be withdrawn when the build-bar is not in its .most elevated posit-ion, the guide 116 does not prevent the build-bar from being raised by the build-rail 13, but engages the bar as soon as the latter starts to descend from its highest position. When the finger 87 is returned to its normal position, the inclined surface 119 (Fig. 20) 'on said finger engages the pin 118 and raises the guide 116 into the position represented in Figs. 14 and 20. 120 (Figs. 14 and 22) is a stop pin to limit the upward movement of the guide, and thus prevent the build-bar from frictionallyraising said guide during the normal operation of the build-bar.

In use, the operator keeps each pair of bobbin-holders supplied with a reserve bobbin, the end of the yarn on said bobbin being placed inthe adjacent clamp 68. Practically all exhausts are caused by the emptying of the bobbin, yarn breakages being relatively infrequent.

Referring to Fig. 9, the running thread holds the detector fork in the position shown in said figure, the detector fork being pressed against the'thread by the spring 89 acting-through the finger 87, the shaft 80, the arm 92, the link 93, the slide 94, the link' 96, the lever 52, and the fork 56. When the thread exhausts, the detector fork moves into the position shown in Fig.' 12, thus allowing the lever 52 to escape from the fork 56, the spring 89 causing the brake to be applied to the flange 107, and the spool frame 83 swinging away from the belt 34. The teeth on the collars 111 112 (Fig. 23) hold the spool frame in such withdrawn position. When the lever 52 moves into the position shown in Fig. 12, the clamp member 47 is swung down into position to clampv the exhausted thread.

When the traveling winder-tending mechanism reaches thelunit, a cam (not shown) on the carriage of said mechanism acts upon the pin 256 (Fig. 10) to swing the stop 254 to the right. Another cam 253 (Fig. 13) on said carriage pushes the slide 94 forward on the guide 95 and thus moves the detector fork 60 into the position shown in Fig. 13,

at the same time moving the clamp member The looper is then permitted to drop upon the thread, the latter passing through the entrance 75 (Fig. 8) into contact with the roller 69. The descent of the looper draws the threads away from the vicinity of the knotter and takes up the slack in said threads. A cam on the carriage then permits the spring 89 to swing the detector 'fork lightly against the new thread, said fork resting against the stop 254 (Fig. 10). As the rear end of the carriage passes the unit, the cam 261 on the carriage withdraws the stop 254, thereby permitting the fork 260 to rest wholly upon the thread. A device on the carriage now permits the looper to descend still farther, whereby the looperdraws thread from the bobbin, thus setting the bobbin in rotation. While the bobbin is thus rotating, a cam on the carriage permits the spring 89 to throw the spool into drivingcontact with the belt 34.

While the present embodiment of the invention has been described with considerable particularity, it will be understood. that the invention is not limited to the construction and arrangement of mechanisms shown.
